I am a little bemused trying to imagine a situation where you would attempt to fire, experience a misfire, and simply make no further attempt to fire. One of the supposed benefits of the Krieghoff cocking system is the ability to recock without opening the breech, always a dangerous thing to do in case a misfire turns out to be a hang fire.

Could you not have simply recocked the action and attempted to fire the left barrel again, or was the shot a fleeting opportunity which vanished before you could recock?
